electric circuit | the path than an electric current follows |
electric current | a flow of electrical charge or electricity through a conductor |
positive to negative | electricity goes from _____ to ____ |
direct current | electric current that moves in one direction only; current that flows through a battery |
circuit | current flow from one terminal to the other in a pathway |
positive to negative | current flows in one direction only, from the ______ terminal to the ________ terminal |
open | type of circuits that obstruct the flow of current |
closed | circuits that allow a pathway to close the loop |
closed | a light bulb is an example of what type of circuit |
conductor | a material that electricity can go through very well; allows current to flow |
insulator | a material that electricity can not go through; needed to fix a break in the circuit |
switch | turns curcuit on or off |
can drain battery | What is bad about short circuits? |
direct | the current that flows from a 9-Volt battery |

open, closed | a switch symbol is always drawn in the ______ position, but it represents a ______ switch |
terminal | the negative or positive end of an electrical cell |
tungsten | material that makes up the filament in a light bulb |
schematic | basic drawing that is universal |
series | circuit in which the electric components are connected in a single loop |
parallel | type of circuit in which components are connected in parallel lines |
series | type of circuit in which the total voltage is divided between components |
DC current | type of current in which the electricity flows only from positive to negative - one direction |
guarantees the resistor is no more than 5% above or below the value at which the resistor is rated | meaning of gold band on a resistor |
parallel | Lamps connected to which type of circuits are brighter? |
parallel | type of circuit in which each lamp has its own pathway to and from the battery |
voltage | force that causes the flow of electric current |
resistance | force that is working against the flow of current |
electricity | flow of electrons in a substance from a high potential of energy to low potential of energy |
electric energy | ability to do work |
power | rate at which electric energy is being used, stored, or transferred |
electron | subatomic particle with a negative charge |
